Given: Circle O with diameter LN and inscribed angle LMN<br> Prove: is a right angle.

skad [1K]

Method 1.

Look at the picture 1.

We have:

$2\alpha=180^o\ \ \ \ |:2\\\\\alpha=90^o$

Picture 2.

$m\angle LMN=90^o$

------------------------------------------------------------------------------------------

Method 2. (Picture 3)

ΔLOM and ΔMON are isosceles triangles. Therefore the two angles opposite the legs are equal.

The sum of the internal angles in each triangle is 180°. Thereofre in ΔLMN we have:

$\alpha+\beta+\beta+\alpha=180^o\\\\2\alpha+2\beta=180^o\ \ \ |:2\\\\\alpha+\beta=90^o$

$m\angle LMN=\alpha+\beta\to m\angle LMN=90^o$

System of Equations: Solve for (x,y) given the system of linear equations "X 1 point

Elenna [48]

Answer:

(x, y) = (4, 0)

Step-by-step explanation:

It looks like you want to solve ...

x - y = 4
x + y = 4

Adding the two equations gives ...

2x = 8

x = 4 . . . . divide by 2

Then ...

y = 4 - x = 0

The solution is (x, y) = (4, 0).

_____

If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.

Dakota read 130 pages over the weekend. Dajuan read 165 pages over the weekend. Which prime number do the prime factorization of

Amanda [17]

In order to find the common prime factors of 130 and 165, let us first find prime factors of 130 and 165 individually and then we can compare.

Prime factors of 130 can be found as:

130 is a composite number because it has factors other than 1 and itself.

It is not a prime number. The 8 factors of 130 are 1, 2, 5, 10, 13, 26, 65, and 130. The factor pairs of 130 are 1 x 130, 2 x 65, 5 x 26, and 10 x 13.

The proper factors of 130 are 1, 2, 5, 10, 13, 26, and 65.

The prime factors of 130 are 2, 5, and 13.

Prime factors of 165 can be found as:

165 is a composite number because it has factors other than 1 and itself. It is not a prime number.

The 8 factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165. The factor pairs of 165 are 1 x 165, 3 x 55, 5 x 33, and 11 x 15.

The proper factors of 165 are 1, 3, 5, 11, 15, 33, and 55.

The prime factors of 165 are 3, 5, and 11.

Answer: On comparing the two, we can see that 5 is the common prime factor of both 130 and 165.

Find the length of the missing side. triangle with an 8 inch side and 12 inch side with a right angle 8.9 in. 104 in. 4 in 14.4

Mamont248 [21]

Given:

In a triangle, length of one side is 8 inches and length of another side is 12 inches, and an angle is a right angle.

To find:

The length of the missing side.

Solution:

In a right angle triangle,

$Hypotenuse^2=Perpendicular^2+Base^2$

Suppose the measures of sides adjacent to the right angle are 8 inches and 12 inches.

Substituting Perpendicular = 8 inches and Base = 12 inches, we get

$Hypotenuse^2=8^2+12^2$

$Hypotenuse^2=64+144$

$Hypotenuse^2=208$

Taking square root on both sides, we get

$Hypotenuse=\sqrt{208}$

$Hypotenuse=14.422205$

$Hypotenuse\approx 14.4$

The length of the missing side is 14.4 inches. Therefore, the correct option is D.
